Troubles with gr-osmosdr on ubuntu

Hi,

I'm trying to make my rtl dongle work with gnuradio 3.6.1 on ubuntu 
12.10. I compiled both recent rtlsdr and gr-osmosdr and all installed 
fine. Right now I have osmosdr on the list of sources in gnuradio and 
want just the example FFT display. When I run it the device gets opened 
without errors but apparently I get no samples, because the plot is 
blank. The dongle is Terratec T Stick PLUS and it works ok with rtl_fm. 
Any hint what can be wrong?

The output when running:

linux; GNU C++ version 4.7.0; Boost_104900; UHD_003.004.002-0-unknown

Using Volk machine: sse3_32_orc
gr-osmosdr supported device types: file osmosdr fcd rtl rtl_tcp uhd
Using device #0 Realtek RTL2838UHIDIR SN: 00000001
Found Elonics E4000 tuner

This may be of interest - strace repeating output:

poll([{fd=4, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=4, revents=POLLOUT}])
writev(4, [{"\20\0\10\0\30\0\200\4_NET_SUPPORTING_WM_CHECK", 32}, {NULL, 
0}, {"", 0}], 3) = 32
poll([{fd=4, events=POLLIN}], 1, -1)    = 1 ([{fd=4, revents=POLLIN}])
recv(4, 
"\1\0\33\f\0\0\0\0\243\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 
4096, 0) = 32
recv(4, 0xa5b6de8, 4096, 0)             = -1 EAGAIN (Resource 
temporarily unavailable)
recv(4, 0xa5b6de8, 4096, 0)             = -1 EAGAIN (Resource 
temporarily unavailable)

Regards, Marek
